Thanks Tim. It'd make a huge difference - I post about 150 galleries of photoshoots for families every year, and managing the reminders for those is going to be super cumbersome. Thanks so much for considering this update, I appreciate it.

The only issue I would have with an automated gallery expiring is that because I do events and bulk photography I can have 200-300 people having viewed a gallery. My web hosting has imposed limits for bulk email and 100 emails in an hour is absolute maximum so I would need some system that not send all emails at once.
